Drying...Fan or Dehumidifier?

I'll be hanging my plants in an garage attic space (big space) at an end close to the attic vent The vent is about a 2 foot circular wall vent.. There isn't great circulation up there..Would I be better off with an oscillating fan or a dehumidifier? Not sure how big a dehumidifier I'd have to find if I need one.

how warm and humid is it there? Dehumidifier wouldnt need to be big just keep it next to the drying buds. I say go for oscillating fan if you can only get one. If it isnt above 50% humidity.

Not sure how hot it is up there in Oregon, but here in Cali it is plenty hot, and any attic will get over 100 degrees. You need to keep the temp around 70-80 degrees for a slow dry so your buds don't taste like grass.

Thanks...Yeah.we are unseasonably warm here where I am now, 77 today and supposed to be sunny and 67-75 for the next 10 days with no rain in sight.(Nice finishing weather for the buds hopefully) I am fighting Powdery mildew from the rain and humid weather we've had the past two weeks though, But by the time I harvest it should be more like usual... low 60's. I'm in central Oregon so it's not as wet as Portland. It would be a lot easier for me to throw a fan up there (I don't have a dehumidifier) In two more weeks being too warm in the attic shouldn't be a problem.
